Thanks Marigold, for the advice and the welcome.
Sadly I can't even get to the log in screen. I only get as far as the tiny little rectangle that says its initialising things, textures ect, when it gets to vps it dissappears and the crash box pops up.
The good news is! I downloaded a different veiwer (pheonix) and I had no trouble getting in with it.
So problem solved sort of, just can't use veiwer 2!
Thanks again for your help!
Cheers,
Lea
